' To at? zr/tm/t 'if may conf-ern.'

Be it known that l, llAttoLn A. YAnNrLL, a citizen ol' the linitetl States, residing at' Escondido. in the eounty of San lliego and State. of (faliiornia. hare invented new and ttset'ttl ltnprtwetnents in Hatter).v Separator-s, of which the following is a speeifieation.

rl`his invention relates to separators ent` ployed hetween the positive and negative plates of storage hatteries and the like, and has tor its ohjett the provision ol :t separal tor whit-h will provide the neeessarbeletA4 trieal insulation while permitting ol' Yl'ree circulation Ut' the elet'trol \'te antl preventing tho clogging o'l the openings for the elet-- trolyte, and also preventing the growth oi mineral deposits. sueh as are lialile to t-attse` internal diseharge ot' the hattenyl The invention contemplates the provision of platesatn'ranged taee to tare and provided with transverse eorrugations tro-oo erating to forni passages through the sepa rator formed hy the plates. whieh will be maintained tree of Sediment. and whirh will provide tor the i'ree eireulation ot tlte eleetrolyte without ittttittg" ol' the separator rfhe intention will lie reatlil)v understood eotnpanhring drawings. in whitfh Figure 1 is a side elevation ot a halter)v partly hrolt'ett away and showing the intprovetl separators in operative position.

Fig. 2 is a detail plan View showinga eorner ot one of the separators.

Fig. 5S is a detail set'tion on the line -i of Fig. 2.

Fig. 4 is a plan View showing the two plates adapted to t'ot'nt :t separator and helore assembling the sante. .d

40 ln the drawingsl have illustrated tht" intprovetl separators as employed hetween the usual battery plates l within a suitahlt hat ter)v easing 2 whieh is adapted to t-ontain a usual electrolyte.

The separators each eomprise tuo plates. sut'h as shown in Fig. 4. and said platt-s may be ot' any suitable insulating material sueh as rubber` eellttloid. and the lil-e Yl`he plates may he molded in the saine fortning apparatus` and eaeh is provided with longitttdinallv extending transverselv spared slots. One of the plates is provided with margins 4. beyond its slots 3, while the other` plate is preferably provided with margins beyond said slots and Ot an appreeiahly greatenwidth, so that when the plates are plaeetl tfaee to tace, the margins l may he t'oltlett over margins l and sttitahl)Y secured thereto as by vnleanizing. eeniettting; ete., in order to maintain the plates in assembled relation to torni a separator.

The strips formed between slots il are provided with medial ribs T projecting from the. plates. and Said strips are Corrugated shown at ts between said ribs and the slots 3. 85 The corrugations are inclined with relation to rihs T, and the eorrugations of each strip at opposite sides ot' the ribs T are angularly disposed with relation to one another, as clearly shown in Fig. 9.. Since the two to 'plates forming the separator are molded in the same apparatus, it will be understood that the eorrugations ol' the plates are sizniA larlyY positioned. as elearl)v shown in Fig. fr.

The ribs T preterahl)y projet-t troni the plates stthstantiall)Y twice the height ot' eor rttgatiotts ti. as clearly shown in Fig. 3, and in assenthling the plates the sante are plat'ed one upon another with the rihs of one plate extending through tlte slotsot' the other plate 80 and overlapping eorrttgations at the sides ot' the ribs of the respeetive plates crossing eaeh other. as elearl)l shown in ltlio.

lt will he noted by rel'erenee to l' l that the slots it are of greater width than ribs l," in order that a 'lree passageway is provided alongside ot the rilis and through the eortu gations ot the plates. It. will he understood that the eorrttgationsot'tlte respeetive plates erossing one another will spat-e said plates so that the eorrugations forni transverse passageways through the assenthled separator. said passage vnys; terminating at the spares alongside ot tht` rihs T.

ln a separator as thus, deserihed. he por- U5 tions thereoi` l'orniing ribs upon one side of the separator and grooves upon the other side thereot will atlzord the desired strength-- ening means for said separator hy means of said ribs. while the grooves will allow tree eireulation ot the eleetrolyte. and will also allow anyv dislodged active material to pass to the bottom ot' the separator. The eorrugations which slant away from the portions Various changes may be mede without departing from the spirit ol the .invention es claimed.

What is claimed is:

1. A. separator comprising overlappingy plates having transverse corrugations 'enl tending toward and abutting against one another for forming openings through seid separator.

2. A. separator comprising overlapping plates having transverse eorrugations engulerly disposed relative to one another so to space seid plates and form openings' through the separator,

3. A separator comprising, overlapping plates having medial rihs Yfacing' one another with the edge ot one plete transversely spaced from the ril) ot' the other plate und transverse eerrngutions in said plates et the sides of said central ribs.

Il. A separator comprising;` overlappingJ plates having medial ribs facing one another with the edge of one phxte transversely spaced from the rih et' the other plate, unil Vtransverse corrugations in said plates at' the sides of seid eentrsilyrilos :ingiilarly disposed relative to one another so es to space said plates and forni openings through the seperater.

5.

6. A separator comprising plates received against one another and eei'h comprising u plurality ot transversely spaced strips leiterally offset relative to one anether, said strips having medial ribs with the ribs of one plate faing the ribs of the other filete and received in the spaces between the strips of the second plete.r seid strips also. having transverse corrugetions et the sides of seid ribs singularly disposed relative to one :in- 'othel` so :1s to space said plates and 'term openings through the separator.
